a)Install the left motion control lever onto the control arm shaft (See Figure 4) on the left side of the console. Place the lever (with the mounting plate towards the rear) on the outside of the control arm shaft and secure with the bolts and washers. Position the lever so the bolts are in the center of the slots on the lever mounting plate and tighten until snug. Repeat on opposite side of unit.

NOTE: There are two lever height options available. Place the levers in the top two holes to increase height of the levers, or in the bottom two holes to decrease the height of the levers.

If the levers do not align with each other when in the neutral position, (See Figure 5) loosen the hardware and make the appropriate adjustment by sliding/tilting the lever(s) forward or backward until properly aligned and tighten hardware.
